Using VWIC 1MFT T1, VWIC 2MFT T1, and VWIC 2MFT T1 DI Interface Cards for Data on Cisco 1700, 2600, 3600 and 3700 Platforms Introduction This document provides an overview of the VWIC 1MFT T1, VWIC 2MFT T1, and VWIC 2MFT T1 DI family of interface cards and provides sample configurations for using this card for data on Cisco 1700, 2600, 3600, and 3700 router platforms. Note: The sample configurations are applicable for data (but not necessarily voice) scenarios. Product Numbers Product VWIC 1MFT T1 VWIC 2MFT T1 Description 1 Port RJ 48 Multiflex Trunk T1 2 Port RJ 48 Multiflex Trunk T1 VWIC 2MFT T1 DI 2 Port RJ 48 Multiflex Trunk T1 With Drop and Insert Features The Multi Flex Trunk (MFT) provides physical layer T1 access. The capabilities of this T1 interface are determined by the host it is plugged into. Voice When you use the Multi Flex Trunk in a high density voice network module, each DS0 can contain voice calls. The voice network module, not the Multi Flex Trunk, determines the T1 signaling capability (T1 CAS, ISDN PRI). 2600 WIC When you use the Multi Flex Trunk in the WAN interface card (WIC) slot of the Cisco 2600 routers, you can configure each T1 into a single channel group as a serial interface. You can have at most two channel groups per VWIC. 3700 WIC When you use the Multi Flex Trunk in the WIC slot of the Cisco 3700 routers, you can configure each T1 into a single channel group as a serial interface. You can have at most two channel groups per VWIC. NM 1E2W, NM 1E1R2W, and NM 2E2W The 3600 NM 1E2W, NM 1E1R2W, and NM 2E2W support one serial channel group per WIC slot, thus the VWIC 2MFT T1 is not supported. The VWIC 2MFT T1 DI is supported, but with one serial channel group. NM 1FE2W, NM 1FE1R2W, NM 2FE2W, and The NM 1FE2W, NM 1FE1R2W, NM 2FE2W and support at most two serial channel groups per WIC slot. Two channel groups on one port This requires Cisco IOS Software Release 12.1(1)T or later on Cisco 2600 routers. This requires Cisco IOS Software Release 12.1(2)X, 12.1(3)T or later releases on Cisco 3620, 3640, and 3660 routers. On the Cisco 3700 routers Cisco IOS Software Release 12.2(8)T or later releases is required.
Two channel groups on one port are supported in Cisco 2600 and Cisco 3700 chassis WIC slots. This is not supported on NM 1E2W, NM 2E2W or NM 1E1R2W but is supported on NM 1FE2W, NM 2FE2W, NM 1FE1R2W and. The WIC slot still supports a maximum of two serial channel groups. When the two channel group mode is enabled only one physical port is supported by the WIC slot. Add and drop multiplexing is still supported in this mode since only one port terminates on the router. Other Features The drop and insert feature on the VWIC 2MFT T1 DI interface card allows you to take DS0 timeslots off one T1 interface and insert them into time slots of the other T1 interface. This feature is available in Voice interface card (VIC) and WIC applications. Future applications may include T1 ATM and T1 ATM CES interfaces. Bit error rate testing (BERT) support requires Cisco IOS Software Release 12.1(1)T or later. V.54 loopback requires Cisco IOS Software Release 12.1(1)T or later.

For data use in 1721/1751/1760, use 12.2(8)YJ. Sample Configuration The sample configuration below is for a VWIC 2MFT T1 card where the first T1 controller (T1 0/0) has timeslots 1 20 (1280k) configured for serial data, and timeslots 21 24 (256k) configured for serial data on the second T1 controller (T1 0/1). Note: Once you configure the channel group 0 timeslot command, a serial interface is created. Configuration! Below is the configuration for the first T1 controller controller T1 0/0 channel group 0 timeslots 1 20 speed 64! Below is the configuration for the second T1 controller controller T1 0/1 channel group 0 timeslots 21 24 speed 64! This serial interface was created from T1 controller 0/0 interface Serial0/0:0 ip address 10.1.1.1 255.255.255.0 encapsulation ppp no shut! This serial interface was created from T1 controller 0/1 interface Serial0/1:0 ip address 10.1.2.1 255.255.255.0 encapsulation ppp no shut Drop and Insert The sample configuration below is for a VWIC 2MFT T1 DI card where the first T1 controller (T1 0/0) has timeslots 1 8 cross connected with timeslots 17 24 on the second T1 controller (T1 0/1).
Note: The following example is for drop and insert of timeslots carrying data. There may be additional configuration options if the timeslots are carrying voice traffic; see the type option for the tdm group command in the command reference. Configuration! Below is the configuration for the first T1 controller controller T1 0/0 clock source line tdm group 1 timeslots 1 8! Below is the configuration for the second T1 controller controller T1 0/1 tdm group 2 timeslots 17 24! Now tie the two tdm groups together! xconnect is simply an arbitrarily chosen tag name connect xconnect T1 0/0 1 T1 0/1 2 Related Information Cisco 1600 Series Routers Cisco 1700 Series Routers Cisco 2600 Series Routers Cisco 3600 Series Routers Cisco 3700 Series Routers Overview of Cisco WAN and Voice Interface Cards Installing WAN and Voice Interface Cards Connecting WAN and Voice Interface Cards to a Network All contents are Copyright 1992 2003 Cisco Systems Inc.
